What is a potential drawback of implementing a queue using an array with a fixed size?
Requirement of complex algorithms for insertion and deletion.
Inability to store elements of different data types.
Risk of queue overflow if the queue reaches its maximum capacity.
Increased time complexity for enqueue and dequeue operations.
What data structure is used to implement a priority queue?
Linked List
Stack
Heap
Array
Which of the following operations on a queue does NOT have a time complexity of O(1) in a standard implementation?
isEmpty
Searching for a specific element
Enqueue
Dequeue
What value does the 'isEmpty' operation on a queue return if the queue contains no elements?
True
-1
The first element in the queue
0
What is the main advantage of using a circular array for implementing a queue compared to a regular array?
Reduced memory consumption
Better handling of sorted data
Faster access to individual elements
Efficient utilization of space after multiple enqueue and dequeue operations
In an array-based queue implementation, what happens when you dequeue from an empty queue?
The queue remains unchanged.
An underflow condition occurs.
The last element is removed.
The first element is removed.
What is the purpose of the 'front' pointer in an array implementation of a queue?
It points to the next available empty location.
It points to the most recently added element.
It points to the element that has been in the queue the longest.
It tracks the total number of elements in the queue.
What is the maximum number of elements a circular queue of size 'n' can hold?
n
n + 1
It depends on the implementation
n - 1
In a queue data structure, what does the 'enqueue' operation perform?
Adds an element to the front of the queue.
Removes and returns the element at the front of the queue.
Adds an element to the rear of the queue.
Checks if the queue is empty.
Imagine a print queue in a busy office environment. Which data structure, implemented using an array, would be most suitable for managing this print queue effectively?
Hash Table
Circular Queue
Binary Tree
